摘要针对正弦信号源捷变状态切换后的建立时间、开机后波形建立时间以及过载恢复时间等的精确测量问题,提出了一种基于局域波形四参数拟合的测量分析方法,然后将拟合模型参数拓展到全局,进而获得拟合回归波形与过渡过程波形的回归残差波形。该波形的收敛过程反映了正弦波建立过程中的残差收敛变化过程。以它为目标对象,加上主观设定的建立时间的条件判据,可以获得正弦建立时间的起始和终止两个时刻点,最终获得完整的正弦信号建立时间。在两组不同条件下的状态切换实验结果,验证了该方法的有效性和可行性。该方法也可以推广应用到脉冲调频、脉冲调幅、脉冲调相、捷变频信号的建立时间测量评价中。

Abstract：Aiming at the problems in accurate measurement of settling time of sinusoidal generator in state changing, switch on, and overloading recovery, a method based on local area four-parameter sine wave curve-fitting is presented. Then, the four fitting parameters are used to the whole area of sampling wave, and the residual error wave between the fitting curve and the sampling wave is gotten. It takes the convergence courses of residual error in settling of sinusoidal. By using this residual error curve, and the condition criterion of the settling time of ourselves, both the beginning time point and the stopping time point are got, finally, the settling time of sinusoidal is calculated. In experiments of two different conditions, both the validity and the feasibility of the measurement method are proved. The method can also be used in settling time measurement of all of the pulse frequency modulation, pulse amplitude modulation, pulse phase modulation, and other digital modulation signal generators.

Key words： metrology sinusoidal hopping frequency frequency agility settling time calibration evaluation curve-fit
